The purchase-comparison record.
A practical sequence for a decision based on the intended use and the evidence you can establish.
1. Describe the job
Write what the purchase needs to make possible and who will use it. Include the setting and the routine around it.
Avoid naming a preferred product before the task is clear.
2. Separate requirements
Mark the conditions without which the option will not work. Keep preferences in another part of the brief.
Explain why a requirement matters so it can be reviewed if circumstances change.
3. Choose comparison lenses
Use the same questions for each option. Include only features that affect the actual use or arrangement.
A longer feature list is not automatically a better comparison.
4. Gather the evidence
Record the original specification, written offer or clarification supporting each important detail.
Keep a broad claim separate from a precise answer to your question.
5. Keep unknowns visible
Write the missing detail and the source that could confirm it. Do not turn uncertainty into a score.
Pause where an essential requirement depends on an unanswered question.
6. Explain the trade-off
State what you gain and give up under the options you are considering. Relate that balance to the job.
Avoid treating your preferred fit as a universal recommendation.
7. Close with conditions
Record the chosen arrangement and what still needs confirmation with the actual provider.
Keep the sources and decision note together so the reasoning remains understandable later.
